HR-45 Superficial Rockwell Hardness Tester
Instruction
HR-45 is an economical superficial Rockwell hardness tester. Simple, reliable and easy to check hardness testing value. Popular in heat treat facility, tool room, workshop, laboratory and inspection lab.
Suitable for surface quenched steel, surface heat treating and chemical treating materials, copper alloy, aluminum alloy, sheet, zinc layers, chrome layers, tin layers, bearing steel and cold and hard casting etc.
Easy Operation & Reliability
Simple product design, easy to operate, stable performance, popular in manufacturing and teaching demonstration
No power supply is required, the speed of applying the test force is adjusted by the hydraulic buffer
The test force transformation is obtained by the rotation of the variable load handwheel
Compatible with most standard Rockwell hardness testers, including HRA, HRB, HRC, HRD, etc.
